Roof Weather-Resistive Barrier with 3D Separation Layer and Self-Adhesive Strip

Advantages

  • High performance monolithic nonporous membrane
  • 3D separation layer provides ventilation between underlay
  • connect technology with two integrated self-adhesive strips
  • High water resistance
  • Low vapour resistance
  • UV resistance up to 30 days

Areas of application

SOLITEX® UM connect is a four-layered roofing underlay with a 3D separation layer and integrated self-adhesive strips for sheet joins. It is suitable for roofing such as titanium, zinc, stainless, galvanised steel and copper. It is also suitable as a weather-Resistive barrier for internal retrofit with existing direct-fix cladding to ensure a gap is maintained between new insulation and the internal side of existing wall cladding.
